Background map not showing in editor

[andmas199]

I want to create a small map of a town in Romania.I've followed this guide (https://www.promods.net/viewtopic.php?t=18827)by a promods' user and I get a texture not found background when trying to use my image. I have uploaded the mod to google drive in case someone can take a look at it and help me: https://drive.google.com/file/d/1u5GWMC ... sp=sharing
Thanks
